In over 3 years I've not used anything other than an open fire or my penny stove.
2 Kronenburg cans - body
Tin lid - primer
Aluminium aircraft repair tape - shield
Wire coathanger - stand
A penny - to block the fill holes
Just used my knife to score open the tins and a hammer and nail for the holes.
4 capfuls of meths is good for 20 mins or so.
